Good points both, but we know good managers try to give their guys ample opportunities to bounce back, find their groove, figure things out, etc. They're usually looking at the long game, and know they need to see if players can improve or be trusted to help out later on, as well.
The thing is, we'll never know how much input/influence/orders come from "the top." Franchy couldn't play outfield, but who specifically made him a first baseman? Who put Arroyo in RF? We know Bloom acquired Schwarber with no place to play him (even at DH), but who shoehorned him into first base... or did the CBO and skipper just look at each other, and shrug: "He can't be worse than Franchy..."
